Popis: This study was conducted to evaluate the effect of thereproductive (multiparous or nulliparous) and climatic (dry orrainy period) conditions on the number and quality of embryoscollected from Boer does. Fifty does, being 33 multiparous and 17nulliparous, were synchronized for oestrus with CIDR® devices fora period of 11 days and superovulated with 250UI of FSH-p. Theanimals were observed for oestrous behaviour at 12 h intervals, afterCIDR® withdrawal. Does were mated and six days later flushedtranscervically to recover the embryos. There was no significantdifference (P>0.05) among the average number of structures andviable embryos recovered from the multiparous and nulliparousfemales. The average number of structures and viable embryosrecovered from multiparous does had no significant difference(P>0.05) between dry and rainy periods. The average number ofstructures and viable embryos classified as G1 recovered fromnulliparous was lower (P
